This option will be available from “Configure Plan + Signup Page” and Addon “Coupon” is required to be activated.
Here, Coupon code will work as “special code / Invite code”.
If this option is enabled then user will get an option to add Coupon Code at time of registration and this will be a compulsory field. So, if you want to make a system to allow registration with some specific invitation code then this option will be helpful.
Once user get logged into system, this code will work normally as coupon code.
If you are setting an “Invite code” with some percent of discount (for example : 10%), then that code will work as both “invitation code” as well as it will give discount (10%) to that user on payment.
